16A Investigation: Magnetism
Key Questions:
What are the effects of
magnetism?
What kinds of materials are
affected by magnetic force?
*Students read text section 16.1
AFTER Investigation 16A
16A Investigation Topics
Measure magnetic force.
Use a compass to detect magnetic force.
Test magnetic properties of various materials.
Chapter 16.1 Objectives and Vocabulary
Recognize that magnetic
poles always exits in pairs.
Decide whether two magnetic
poles will attract or repel.
Describe the magnetic field
and forces around a
permanent magnet.

Chapter 16.2 Objectives and Vocabulary
Learn how to build a simple
electromagnet and change
its strength.
Use the right-hand rule to
locate an electromagnet's
poles.
Explain the source of
magnetism in materials.

Right-Hand Rule
If the fingers of your
RIGHT hand curl in
the direction of the
current, your thumb
points toward the
north pole.
Where is the north and south pole?
